The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions.

The efficacy of octreotide therapy in chronic bleeding due to vascular abnormalities of the gastrointestinal tract. (1/43)
BACKGROUND: The treatment of angiodysplasia and watermelon stomach, vascular abnormalities implicated in gastrointestinal bleeding of obscure origin, is a major clinical problem. AIM: To determine the efficacy of octreotide in patients with long-standing gastrointestinal bleeding due to acquired angiodysplasia and watermelon stomach, resistant to previous treatments and not suitable for surgery because of old age and/or concomitant disorders. PATIENTS AND METHODS: We treated 17 patients (seven had isolated angiodysplasia, seven had multiple upper and lower gastrointestinal angiodysplasia, and three had watermelon stomach) with octreotide (0. 1 mg subcutaneous t.d.s. for 6 months). Six of the patients had liver cirrhosis, one had Glanzmann-type platelet derangement, two had cardiovascular diseases and one had chronic uraemia. RESULTS: Octreotide treatment stopped bleeding in 10 patients. A transient improvement was observed in four, who needed subsequent cyclical retreatment to correct low haemoglobin levels. No effect was observed in three, probably due to the severity of the concomitant disorders. CONCLUSIONS: Octreotide is a safe drug that may be useful to control the recurrent gastrointestinal bleeding due to acquired angiodysplasia and watermelon stomach, especially in patients who are not candidates for surgery due to old age and/or concomitant disorders. (+info)Diffuse angiodysplasia of the upper gastrointestinal tract in a patient with hypertrophic obstructive cardiomyopathy. (2/43)
A 64-year-old woman with a known history of hypertrophic obstructive cardiomyopathy presented with severe anemia of unknown origin. She had also suffered from repeated episodes of upper gastrointestinal bleeding for the previous 3 years. Despite bone marrow examination and panendoscopic and angiographic studies, the origin of anemia remained undefined until a small bleeding site was found during a duodenoscopic examination. The lesion proved to be angiodysplasia. This case report is interesting in that angiodysplasia elicited gastrointestinal bleeding and was the cause of anemia. In the international literature, there are very few reported cases of bleeding from gastrointestinal angiodysplasia in association with subvalvular aortic obstruction. (+info)Skeletal angiomatosis in association with gastro-intestinal angiodysplasia and paraproteinemia: a case report. (3/43)
Skeletal-extraskeletal angiomatosis is defined as a benign vascular proliferation involving the medullary cavity of bone and at least one other type of tissue. It has also been known as cystic angiomatosis in which multiple cystic lesions are scattered diffusely throughout the skeleton often with similar angiomatous changes in other tissues, usually the spleen. A case of skeletal angiomatosis in association with gastro-intestinal angiodysplasia and paraproteinemia is reported. (+info)Rate and predictive factors of rebleeding with obscure-overt gastrointestinal bleeding. (4/43)
BACKGROUND/AIMS: Little information is available on the rate and predictive factors of rebleeding of unknown cause, which is very important in deciding further investigations on obscure-overt gastrointestinal bleeding. The aim of this study was to evaluate the rebleeding rate and related factors in obscure-overt gastrointestinal bleeding patients who revealed normal gastroscopic and colonoscopic findings. METHODS: A total of 69 patients with negative first-line gastroscopy and colonoscopy were enrolled in this study as obscure-overt gastrointestinal bleeding cases. The relationships between rebleeding and clinical characteristics were analyzed retrospectively. RESULTS: The causes of obscure-overt gastrointestinal bleeding were confirmed in 30 cases among the 69 cases. Small bowel tumors (14 cases) were the most common cause, followed by vascular lesions (6 cases). The mean follow-up period was 28 months and rebleeding was noticed in 19 patients (27.5%). Among these rebleeding patients, 14 cases (73.7%) occurred within 6 months. The past experience of previous bleeding was significantly related with rebleeding (p=0.0009). CONCLUSIONS: Close observation and detailed investigations are needed for obscure-overt gastrointestinal bleeding patients with bleeding history, especially during 6 months follow-up. (+info)Persistent anemia in otherwise asymptomatic severe aortic stenosis: a possible indication for valve replacement? (5/43)
BACKGROUND: The indication for aortic valve replacement in patients with significant aortic stenosis is symptomatology. Aortic stenosis may be associated with bleeding from colonic angiodysplasia, resulting in anemia. Persistent anemia in such patients, despite lack of an identifiable source of bleeding, is not considered an indication for valve replacement. OBJECTIVES: To report our experience with two elderly female patients who suffered from severe asymptomatic aortic stenosis, low levels of large von Willebrand factor multimer (10% and 5% respectively) and persistent anemia requiring multiple blood transfusions. METHODS: Both patients underwent an intensive work-up, but a source of bleeding could not be identified. Aortic valve replacement was performed in both patients. RESULTS: Aortic valve replacement abolished the need for further blood transfusions during a follow-up period of 20 months with normalization of the vWF multimer level (20% and 30% respectively). CONCLUSION: We suggest that aortic valve replacement be considered in selected patients with severe, otherwise asymptomatic aortic stenosis, who suffer from persistent anemia requiring multiple blood transfusions, lack an identifiable source of bleeding and have low levels of large vWF multimers. (+info)Myelofibrosis and angiodysplasia of the colon: another manifestation of portal hypertension and massive splenomegaly? (6/43)
Bleeding owing to portal hypertensive colopathy, a form of large bowel angiodysplasia, as a cause of increased blood transfusion requirement is described in a 74 year old man with idiopathic myelofibrosis. The proposed mechanism and the potential therapeutic options for this rare complication of myelofibrosis are discussed. (+info)Infective endocarditis from Enterococcus faecalis complicating colonoscopy in Heyde's syndrome. (7/43)
A case of infective endocarditis from Enterococcus faecalis after colonoscopy in a patient with aortic stenoinsufficiency and bleeding intestinal angiodysplasia (Heyde's syndrome) is reported.A 77 year old man with aortic stenoinsufficiency presented with enterorrhagia and underwent a colonoscopy, which showed normal findings. Fifteen days later he developed a moderate degree of fever. Blood cultures were positive for E faecalis. An echocardiogram showed aortic valve vegetations, and infective endocarditis was diagnosed and successfully treated by antibiotics. Some months later, intestinal bleeding recurred and intestinal resection was performed. Histopathology showed angiodysplasia. In patients with Heyde's syndrome antibiotic prophylaxis should be considered before colonoscopy. (+info)Successful colectomy for the treatment of repetitive bleeding from colonic angiodysplasia in a patient with Heyde syndrome. (8/43)
A 64-year-old man with repetitive gastrointestinal bleeding was admitted to our hospital. Colonic artery angiography revealed angiodysplasia as the bleeding site, and echocardiography showed aortic valve stenosis. A decrease in the high molecular weight von Willebrand factor multimers, which are known to play an important role in hemostasis, was observed, and Heyde syndrome was diagnosed. We selected colectomy instead of aortic valve replacement because the patient had undergone two open heart surgeries. Following colectomy, the patient showed a good clinical course without recurrent gastrointestinal bleeding. Colectomy might serve as a therapeutic option for Heyde syndrome after the precise site of angiodysplasia is detected by angiography. (+info)... refers to changes in the mucosa of the stomach in patients with portal hypertension; by far the most common cause of this is cirrhosis of the liver. These changes in the mucosa include friability of the mucosa and the presence of ectatic blood vessels at the surface. Patients with portal hypertensive gastropathy may experience bleeding from the stomach, which may uncommonly manifest itself in vomiting blood or melena; however, portal hypertension may cause several other more common sources of upper gastrointestinal bleeding, such as esophageal varices and gastric varices. On endoscopic evaluation of the stomach, this condition shows a characteristic mosaic or "snake-skin" appearance to the mucosa of the stomach. Most patients with portal hypertensive gastropathy have either a stable or improving course in the appearance of the gastropathy on endoscopy. However, according to retrospective data, roughly one in seven patients with portal hypertensive gastropathy will ...
... (exulceratio simplex Dieulafoy) is a medical condition characterized by a large tortuous arteriole most commonly in the stomach wall (submucosal) that erodes and bleeds. It can present in any part of the gastrointestinal tract. It can cause gastric hemorrhage but is relatively uncommon. It is thought to cause less than 5% of all gastrointestinal bleeds in adults. It was named after French surgeon Paul Georges Dieulafoy, who described this condition in his paper "Exulceratio simplex: Leçons 1-3" in 1898. It is also called "caliber-persistent artery" or "aneurysm" of gastric vessels. However, unlike most other aneurysms, these are thought to be developmental malformations rather than degenerative changes. Dieulafoy's lesions are characterized by a single large tortuous small artery in the submucosa which does not undergo normal branching or a branch with caliber of 1-5 mm (more than 10 times the normal diameter of mucosal capillaries). The lesion bleeds into the ...
... , also known as pseudohematobilia or Wirsungorrhage is a rare cause of hemorrhage in the gastrointestinal tract. It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct, which is connected with the bowel at the duodenum, the first part of the small intestine. Patients with hemosuccus may develop symptoms of gastrointestinal hemorrhage, such as blood in the stools, maroon stools, or melena, which is a dark, tarry stool caused by digestion of red blood cells. They may also develop abdominal pain. It is associated with pancreatitis, pancreatic cancer and aneurysms of the splenic artery. Hemosuccus may be identified with endoscopy (esophagogastroduodenoscopy), where fresh blood may be seen from the pancreatic duct. Alternatively, angiography may be used to inject the celiac axis to determine the blood vessel that is bleeding. This may also be used to treat ...
... (sometimes spelled oesophageal varices) are extremely dilated sub-mucosal veins in the lower third of the esophagus. They are most often a consequence of portal hypertension, commonly due to cirrhosis; patients with esophageal varices have a strong tendency to develop bleeding. Esophageal varices are typically diagnosed through an esophagogastroduodenoscopy. The upper two thirds of the esophagus are drained via the esophageal veins, which carry deoxygenated blood from the esophagus to the azygos vein, which in turn drains directly into the superior vena cava. These veins have no part in the development of esophageal varices. The lower one third of the esophagus is drained into the superficial veins lining the esophageal mucosa, which drain into the left gastric vein (coronary vein), which in turn drains directly into the portal vein. These superficial veins (normally only approximately 1 mm in diameter) become distended up to 1-2 cm in diameter in association with portal ...
... (GI bleed), also known as gastrointestinal hemorrhage, is all forms of bleeding in the gastrointestinal tract, from the mouth to the rectum. When there is significant blood loss over a short time, symptoms may include vomiting red blood, vomiting black blood, bloody stool, or black stool. Small amounts of bleeding over a long time may cause iron-deficiency anemia resulting in feeling tired or heart-related chest pain. Other symptoms may include abdominal pain, shortness of breath, pale skin, or passing out. Sometimes in those with small amounts of bleeding no symptoms may be present. Bleeding is typically divided into two main types: upper gastrointestinal bleeding and lower gastrointestinal bleeding. Causes of upper GI bleeds include: peptic ulcer disease, esophageal varices due to liver cirrhosis and cancer, among others. Causes of lower GI bleeds include: hemorrhoids, cancer, and inflammatory bowel disease among others. Diagnosis typically begins with a medical ...
Fresh Blood" featured the final guest appearance by Sterling K. Brown as the vampire hunter Gordon Walker. The character's story arc for the season was intended to be longer, but Brown's commitments to the Lifetime Television series Army Wives limited his return to only two appearances.[2] The episode was "really hard" for the actor; though he was fine with the character dying, the idea of Gordon turning an innocent girl into a vampire was "horrific" to him.[3] Although Gordon's actions in previous episodes were questionable, Brown had always believed the character to be "ultimately good".[4] On this change, Brown commented, "His endgame is to kill Sam, and anyone else who has to experience detrimental effects because of that is not a concern of his. That was tough for me to process and get on board with."[3] However, series creator Eric Kripke reasoned that the character was now a monster and should follow his instincts instead of logic.[3] The writer of "Fresh Blood", Sera Gamble, also penned ...

Argon is a chemical element. The symbol for argon is Ar, and its atomic number (or proton number) is 18. It is a noble gas and no electrons or protons can be lost or gained from this atom. Argon atoms are found in air. About 1% of the Earth's atmosphere (the air around us) is argon. ...
... is a benign condition, usually found in older men, involving numerous small, tubular cystic structures within the rete testis. The formation of cysts in the rete testis is associated with the obstruction of the efferent ducts, which connect the rete testis with the head of the epididymis. They are often bilateral. The condition can be detected with sonography. It is commonly associated with epididymal abnormalities, such as spermatocele, epididymal cyst, and epididymitis. The condition shares a common location with cystic dysplasia of the testis and intratesticular cysts. Unlike cystic neoplasms, they don't present specific tumor markers. Typically none is required, but they can be treated surgically if symptomatic.

... , also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. Either the small bowel or large bowel may be affected. Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. Mechanical obstruction is the cause of about 5 to 15% of cases of severe abdominal pain of sudden onset requiring admission to hospital. Causes of bowel obstruction include adhesions, hernias, volvulus, endometriosis, inflammatory bowel disease, appendicitis, tumors, diverticulitis, ischemic bowel, tuberculosis and intussusception. Small bowel obstructions are most often due to adhesions and hernias while large bowel obstructions are most often due to tumors and volvulus. The diagnosis may be made on plain X-rays; however, CT scan is more accurate. Ultrasound or MRI may help in the diagnosis of children or pregnant women. The condition may be treated conservatively or with surgery. ...
There are two colic flexures, or curvatures in the transverse colon. The one on the right, the right colic flexure is known as the hepatic flexure. The one on the left, the left colic flexure is known as the splenic flexure. The right colic flexure or hepatic flexure (as it is next to the liver) is the sharp bend between the ascending colon and the transverse colon. The hepatic flexure lies in the right upper quadrant of the human abdomen. It receives blood supply from the superior mesenteric artery. The left colic flexure or splenic flexure (as it is close to the spleen) is the sharp bend between the transverse colon and the descending colon. The splenic flexure is a watershed region as it receives dual blood supply from the terminal branches of the superior mesenteric artery and the inferior mesenteric artery, thus making it prone to ischemic damage in cases of low blood pressure because it does not have its own primary source of blood. In the context of ischemia, the splenic flexure is ...
... or malacoplakia (from Greek Malako "soft" + Plako "plaque") is a rare inflammatory condition which makes its presence known as a papule, plaque or ulceration that usually affects the genitourinary tract. However, it may also be associated with other bodily organs. It was initially described in the early 20th century as soft yellowish plaques found on the mucosa of the urinary bladder. Microscopically it is characterized by the presence of foamy histiocytes with basophilic inclusions called Michaelis-Gutmann bodies. It usually involves gram-negative bacteria. Malakoplakia is thought to result from the insufficient killing of bacteria by macrophages. Therefore, the partially digested bacteria accumulate in macrophages and leads to a deposition of iron and calcium. The impairment of bactericidal activity manifests itself as the formation of an ulcer, plaque or papule. Malakoplakia is associated with patients with a history of immunosuppression due to lymphoma, diabetes mellitus, renal ...
